DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a container for filling a substance which solidifies at room temperature or becomes a viscous liquid in a liquid state, and after transporting, discharges the substance in a liquid state when used. It relates to the transport method used.

More specifically, the present invention is provided with a coil capable of internal heating, a stirring shaft and a stirring blade, a stirrer drive motor is attached to the stirring shaft at the time of discharging, and containers can be stacked in multiple stages vertically and stacked. By using a container with a structure that can use a forklift in the state, and filling the container with the contents as a molten liquid, after transporting, connecting a drive motor to a stirring shaft, heating, stirring, and discharging the contents in a liquid state, The present invention relates to a method of filling, transporting, and discharging a substance which solidifies at room temperature or becomes a viscous liquid.

[Prior art] Although the melting point is higher than room temperature and it is a liquid at the temperature of the manufacturing process, there are very many chemical products and foods that solidify or become a viscous liquid when the temperature is lowered to room temperature. There are a number of problems as the material is transported and solidifies in the container or becomes a viscous liquid. In particular, after transportation, it is difficult to take out the contents for use at the destination.

Conventionally, the following methods have been used as a method for filling, packaging, and transporting such a substance.

(A) The product is solidified in the form of flakes, beads, pellets, powders, and the like, packaged in a cement bag or the like, and transported.

(B) Inject and fill in a molten liquid into a drum or can and transport it.

(C) The molten liquid is stored in a storage tank, poured into a tank truck or the like according to an order, and transported in the molten liquid.

However, in the method (a), equipment and manpower are required for a solidification step such as pelletization, and manpower is required to melt the solidification step. Further, since the surface area is increased, there is a problem that some products are subject to deterioration due to moisture absorption or oxidation deterioration.

In addition, in the method (b), in order to melt the solidified product at the time of use, not only a special device such as heating a container in a greenhouse or heating in a hot water tank is required, but also huge energy is required. Consumed.

In the method (c), it is not only difficult to adopt the method because the efficiency is low unless the shipment amount per one time reaches a certain level or more.
There is a problem that it cannot be used for thermally unstable substances because it is held in a molten liquid for a long time.

[Problems to be Solved by the Invention] The present invention solves the above-mentioned drawbacks of the prior art, and solidifies at room temperature and becomes a viscous liquid. When transporting substances that need to be made into fine shapes such as flakes and powders, and even when transporting products on a scale that does not reach the volume required to receive and use the molten liquid with a tank lorry An object of the present invention is to provide a method of manufacturing a container and a method of filling, transporting and discharging the product using the container.

The substance is liquid at high temperature, but solidifies when cooled to room temperature or becomes a viscous liquid in a container, and if it does not take the form of transportation in a molten state like a tank lorry, it is transported to the destination Later, the contents must be melted out and transferred to a reactor or storage tank for use.

In such a case, even if the container is heated using internal heating means built into the container to improve the heating efficiency of the container, it takes a long time to melt the entire solid or viscous liquid. In addition, a stirrer is required because there is a possibility that the product is deteriorated due to local overheating.

However, it is uneconomical to install each stirrer in such a not so large container, and there are many troubles such as damage to the stirrer during transportation. Especially two containers
It is inconvenient when transporting in stacks of more than one step.

Further, even if the stirrer is mounted only at the time of discharge, it cannot be mounted in a solidified state.

The inventor examined this point and found that the drive motor was removed from the stirrer.If only the stirrer shaft and stirrer blades were installed in each container, it would not be economically disadvantageous. Even if the contents solidify as it is, there is no effect on the stirring blades, and if heated in advance, smooth stirring can be achieved, and the connection and disconnection of the stirring shaft and drive motor during filling and transport, and during discharging. Can be extremely simple, and if the drive motor is removed, the height of the container bottom plate, the height from the ceiling plate to the top of the connection end with the drive motor, and the height of the nozzle attached to the top of the ceiling plate By adjusting the positional relationship, containers can be stacked in multiple stages up and down, and based on the knowledge that forklifts can be used in the stacked state, As a container for filling and transporting solidified in temperature, or a viscous liquid material,
Remove the stirrer drive motor, prepare a container with only the stirring shaft and stirring blades, fill the above container with the product, transport it to the destination, attach the motor of the stirrer to the container, and heat the container with stirring Discharging the product to save energy not only speeds up the process, but also prevents product degradation, and eliminates the need to install a stirrer drive motor in each container, as well as filling and transporting. It has been found that the replacement of the device at the time and at the time of discharge is very simple, and that the entire device for transportation can be greatly rationalized.

[Means for Solving the Problems] That is, the structure of the container of the present invention at the time of filling and transporting is as follows:
A stirring shaft having a stirring blade at a lower portion; (b) a heating or heating / cooling coil installed at a peripheral portion and a bottom portion of the stirring blade; (c) an inlet for filling a liquid; Equipped with a discharge port, and the height from the corner post feet to the bottom of the container bottom plate is higher than the height from the ceiling plate to the top of the connection end with the drive motor, and attached to the top of the ceiling plate All the nozzles are installed in the vicinity of the center line in the insertion direction of the forklift, and a space is provided between the vertically stacked containers for insertion of forklift claws.

Then, the content is poured into a container having the above structure as a molten liquid, and the molten liquid is transported in a solid or viscous liquid state.After transport, a drive motor is attached to a stirring shaft, the content is melted by passing steam through a coil, and the mixture is stirred. After the wings are immersed in the molten liquid, the stirrer drive motor is started to stir the molten liquid,
By discharging the contents as a molten liquid, filling, transporting, and discharging of a substance that solidifies at room temperature or becomes a viscous liquid are effectively performed.

The size of the container of the present invention is not particularly limited. However, considering the purpose of the present invention, the size of the container is smaller than that of the tank lorry, and is suitably large enough to be transported by a forklift.

An example of the structure of the container of the present invention will be described with reference to the drawings. 1 is an overall perspective view, FIG. 2 is a plan view, and FIG. 3 is a side view. The container is formed in a box shape by an inclined floor panel 1 (bottom panel), a roof panel (ceiling panel) 2, and outer peripheral panels 3 and 4 composed of both end panels and both side panels, each corner having a foot 5 at each corner. A post 6 and a reinforcing frame 7 are provided.

The stirring shaft 20 of the stirrer penetrates through the center of the ceiling plate,
A stirring blade 19 for melting and stirring the contents is attached below the stirring shaft, that is, inside the container. (The stirring shaft and the stirring blade are not shown in FIG. 1.) At the upper part of the stirring shaft, there is a connection end 22 with a driving motor, but the driving motor is not attached during filling and transportation. Normally, a manhole 10 is provided at the center of the ceiling plate for inspection of the inside of the container and the like, and the stirring shaft of the stirrer is installed in this manhole. A removable cap (not shown) may be attached as needed to protect the connection end between the stirring shaft and the drive motor. It is installed on the bottom plate. The ceiling plate is provided with a nozzle 12 for ventilation and introduction of an inert gas.

The liquid outlet 14 is normally closed by a blind flange (not shown), but the valve is closed if the product is drained before it is completely solid.

The heating of the container is carried out by steam or electric heating, and both are coiled and installed at the periphery of the spacer and at the bottom of the container. 1 to 3 show an example of a steam heating container, which is steam heated by a coil 17. The coil 17 can also introduce cooling water after injecting the product, which has the effect of rapidly cooling the container and preventing the product from deteriorating. That is, in the case of steam heating, the coil 17 can be a heating / cooling coil. In this regard, steam heating is preferred. The nozzles 13 and 15 are nozzles for introducing and discharging steam and cooling water. A thermometer seat 18 for measuring the temperature of the contents is provided on the outer peripheral panel. It is desirable to be installed.

In order to prevent damage during transportation, it is desirable that the blind flange 15, the steam discharge port, and the like be accommodated inside the outer peripheral panel.

In FIG. 4, 21 is a drive motor unit, 20 is a rotating shaft unit,
Reference numeral 19 denotes a stirring blade, and reference numeral 22 denotes a connection end between the stirring shaft and the drive motor. However, the container of the present invention does not have a drive motor at the time of filling and transportation, but is attached only at the time of discharge.

Further, the container of the present invention can be structured to increase the efficiency of transportation and storage.

In order to save storage space, it is necessary that the containers have a structure that can be stacked in upper and lower tiers. In order to transport a container of this size, it is most efficient to transport the container by a forklift, and a structure in which the forklift can be used in a stacked state is desirable.

The structure of the container of the present invention allows such stacking,
Moreover, the forklift claws can be inserted in a stacked state.

That is, feet 5 are attached to the four corners at the bottom, whereby the height (h ₁ ) of the lowermost corner post of the inclined container bottom plate from the feet is measured from the ceiling plate to the top of the connection end of the drive motor. (H ₂ ), and all nozzles such as a liquid inlet 11, a vapor inlet nozzle 13, and a nozzle 12 for ventilation and inert gas introduction, which are mounted on the upper part of the ceiling plate, are mounted on the forklift in FIG. Near the container center line XX 'in the insertion direction, preferably 40 cm from the center line
It is desirable to set it within 20 cm, particularly preferably within 20 cm. By doing so, the containers can be stacked up and down, and the claw of the forklift is inserted outside the centerline in the forklift insertion direction or the manhole and the nozzles installed near the centerline in the vicinity thereof, There is no problem in transportation. In addition, in order to prevent the containers from slipping off when stacking the containers, sliding stop corner stoppers 16 are provided at four corners of the reinforcing frame 7 of the ceiling plate as shown in FIG. Match with foot 5 when stacking.

An example of the method of filling, transporting and discharging the product by the container of the present invention will be described below.

The connection end 22 with the drive motor at the top, stirring blade 19 at the bottom
A container having a stirrer shaft section 20 having the following structure attached to the manhole 10 is prepared at the production site of the product, and a blind flange or a valve is attached to the outlet 14. The container is placed on the weighing machine by a forklift, and a predetermined amount of the product is injected into the container from the liquid injection port 11 in a molten state. In the case of products that are sensitive to heat and easily deteriorate, let cooling water pass through the nozzle 13 and
Water is also discharged to the outer peripheral panel as needed to cool the container, and if necessary, the container is stored and cooled in a refrigerator.

The container filled and solidified as described above is regularly loaded on a truck by a forklift and transported to the destination.

The container arriving at the place of use of the product is placed on a weighing machine by a forklift, and a stirrer drive motor 21 prepared in advance at the place of use is connected to the connection end 22 of the stirring shaft 20. Remove the blind flange 15 of the outlet, attach the required valve and flexible hose, and connect to the feed line of the facility that uses the contents of the container. Next, after attaching a steam trap to the steam outlet 15, the nozzle
From 13 introduce steam into the coil. After the contents are melted by the steam heating and the area around the stirring blades 19 of the stirrer is in a molten state, the stirrer drive motor is started to increase the heat transfer efficiency from the steam coil 17 and accelerate the melting. After confirming that the whole is melted by the thermometer inserted in the slowest melting portion, the stirrer is stopped, and a predetermined amount of product is discharged by the weighing device on which the container is placed.

Materials transported using the container of the present invention include:
Normally, the melting point is not less than normal temperature and 120 ° C. or less, preferably 90 ° C. or less, or a substance whose melting point is not more than normal temperature but has a remarkably high viscosity, and a substance whose viscosity is significantly reduced by increasing the temperature.
Particularly, a solid having a melting point of not higher than room temperature and not higher than 80 ° C. is suitable. Such substances include fatty acids, fatty acid esters, hardened edible oils, aliphatic amines, polyglycerin and its esters, polyether and its derivatives, dimer acid, alkyl ketene dimer, polybutene, synthetic resin latex, molasses, starch syrup, petroleum-based Pitch and the like can be exemplified.

[Effects of the Invention] The present invention is a container having a structure that has a coil capable of internal heating, a stirring blade and a stirring shaft, and a stirrer driving motor can be attached at the time of discharge, whereby a stirrer driving motor is provided for each container. No need to install
Container equipment costs can be saved, and downsizing is achieved, and troubles such as damage to the agitator drive motor during transportation can be avoided.

Also, the height of the container bottom plate to the bottom is higher than the height from the ceiling plate to the top of the connection end to the drive motor, and all nozzles attached to the top of the ceiling plate are aligned with the center line in the insertion direction of the forklift. The agitator drive motor is removed in the vicinity, and the stirrer drive motor is removed during transport, so containers can be stacked in multiple stages up and down, and forklifts can be used in the stacked state, saving storage space and improving transport efficiency In addition, since the stirring blade and the stirring shaft are attached when the contents of the container are solidified, stirring can be performed immediately with a very simple operation just by installing the drive motor. Insufficient heating can be performed effectively, the product can be melted and discharged quickly, streamlining the process and saving Power, energy saving, and prevention of product deterioration due to heat are possible. Further, no labor is required for flakes and pellets, and it is possible to prevent deterioration in quality due to moisture absorption and oxidation accompanying an increase in surface area. Further, the product can be easily transported even in an amount less than the size suitable for transporting by tank lorry, and since it is not stored in a molten state, it can be used as a temporary storage tank without fear of product deterioration.

Since the present invention has many advantages as described above, it can be widely used as a method for transporting chemical products, foods and the like which solidify at room temperature or become viscous liquid.
